Just buy them anyway & use the extra few hp to your advantage.

Mind you at 63 seconds for the short track, can I suggest some tyre & suspension work first?

Agreed! Suspension setup before power for the track. + driver mods too.

What do mean 'just buy them'? Can I use them with the Poncams later?

Damn you lot, I havent the money for this handling stuff :P

I will get Sydneykids Bilstein kit and Nismo front and rear swaybars and strut braces when I have the money. And if I scrap my idea of getting the Do Luck kit, I could get all that handling stuff very soon.

No they don't. But the lobe centres on the cam are different to the Nissan ones.

To change the timing belt you have to take the water pump out. Given how cheap they are it is one of those may as well do it jobs.

You dont have to take out the pump to change the timing belt,although its easier when everythings off..

Topaz have you ever changed a timing belt?

If you haven't got the proper tools I'd just let Ken do it for you :P

My dad has done it many times before (he's also a Fitter/Turner by trade) and he thinks we don't need a timing light :P

Everyone else thinks for RB engines to use a timing light!

Ok guys here is the deal HKS cam gears only have a 3 bolt locking system for the adjustment and they tend to wear out on the tooth section from the cam belt alot faster than any other cam gears on the market.

As a rule i use Tomie cam gears because they have a 4 bolt system and sometimes a 5 bolt system for locking they adjustment up on some vehicles. This is extreemly important at high revs as we all no what happens if your cams move at 8000rpm's...... big damage to your engine. Tomie also have the better of the durilium manufacturing and in my experience seem to last alot longer than its competitors...

At the end of the day its personal choice but i hope that some of this helps in your decisison.

Take care and good luck.

yeah thats some good info, but my question can u make more power by just changing cams? or are they only good when coupled with other mods?

Yes, should give you a decent power gain even with a relatively stock car. I know poncams, HKS step 1 etcs are usually designed so that they can be run with a stock computer and give a decent gain.

I did my own timing belt, and for the price of a new engine over a timing light guess which one I'd choose.

P.S. Do please do your water pump at the same time, for 140bux or whatever they are it's well worth it. My Water pump died, so I did my timing belt (again) for the extra money.

designed to run on stock ecu map ------> no

gain power on stock ecu? -------> no

will plugs foul very quickly using standard ecu and these cams ------> yes

will fuel ecconomy be crap using standard ecu -------> yes

Should I get a power FC first ---------> yes

Also on the HKS cam gear wearing out myth. How many worn out HKS cam gears has anyone seen, can we count 30? if not its not even statistically valid. I say nothing wrong with them in fact they are alot easier to adjust than the tomie ones too, I've had both I'd personally buy the HKS ones or something similar next time round (2c)

If you are thinking about new cams at any stage you can give the adustable pulleys a miss as the Poncams (To use but one example) have different centres to the stock items & you don't get such a gain from playing around with them.

Sorry disagree about the poncams not benifiting 'greatly' from being able to alter the cam timing with adjustable gears.Along with many others I have experienced the benifit of doing so on both stock and group A turbos on the RB26.

In partnership with adjustments to the timing and fuel maps changes can be made to the power curve and boost response.

      That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      Blue slip

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
